Raise arms to side with thumb side up. Lower and repeat.
Comments
Maintain straight elbow position throughout exercise. Exercise may also be performed with shoulders traveling up to 30º forward, more inline with plane of scapulas.
Supraspinatus activity is similar between 'empty can' and 'full can' exercises. However, 'full can' results in less risk of subacromial impingement. Scapular internal rotation and scapular anterior tilt, both of which decrease subacromial space width and increase impingement risk, are greater when performing scaption with shoulder internal rotation (empty can) compared with scaption with external rotation (full can ). (Escamilla 2009)
